Abstract (en)
[origin: EP3406322A1] The objective of the present invention is to provide an exhaust gas purification device which has improved exhaust gas purification performance. An exhaust gas purification device (100) which comprises a first catalyst layer (2) that contains: a Pd-supporting catalyst which is obtained by having alumina carrier particles (22) support Pd (21); a first Rh-supporting catalyst which is obtained by having first ceria-zirconia carrier particles (23) support Rh (24); and second ceria-zirconia carrier particles (25). This exhaust gas purification device (100) is configured such that: the ceria concentration in the first ceria-zirconia carrier particles (23) is 30 wt% or less; and the amount of ceria in the second ceria-zirconia carrier particles (25) is larger than the amount of ceria in the first ceria-zirconia carrier particles (23).
